Paul Bruchal Posted August 10, 2015 Share Posted August 10, 2015 The wiring in my MJ is... ruined, from last owner. Do yall think it would be alright for me to directly wire the stereo a constant 12v and ground, and just turn off the stereo when not using it? The last owner had something rigged up like that.. the little red light was on 24/7 and all you had to do was hit the power button to listen. No keys required. If yall think I should try to wire it the right way. Could someone please show me a wiring diagram for a 1988 MJ that you used. I been looking at different diagrams all morning and they are all different. Link to comment Share on other sites More sharing options...

Crash Posted August 12, 2015 Share Posted August 12, 2015 I think that you will need a diagram to wire proper anyways, but in my XJ I have the constant/"ign" power wires together running to the constant (which IIRC is the pink wire) with an inline fuse. Your HU might have a fuse in it, if not definitely run an inline fuse. I always detach the face, which cuts power to the HU. SO that is fine.
